Advantages of Heat Shrink Tubing Gluing/Coating Machines: Precision Coating Uniform adhesive layer (spray/spiral technology), eliminating weak spots. Enhanced Bond Strength Optimized adhesion for waterproofing, insulation, and corrosion resistance. High Efficiency Continuous operation (up to 12m/min), ideal for mass production. Custom Flexibility Adjustable parameters (glue volume, temperature, speed) for tubes ≤1.5m. Material Versatility Compatible with PE, PP, EVA, and cross-linked polyolefin tubes. Waste Reduction Precise glue application minimizes material overuse. Seamless Integration Fits inline with extrusion/cutting systems for end-to-end automation. Core Impact: Boosts product reliability while cutting production costs 15–30%.

HST Pre-cut Expansion is a specialized manufacturing process used to produce high-quality heat shrink tubing (HST) with precise final lengths and consistent performance. This method is particularly crucial for applications demanding exact dimensional tolerances and minimal material waste.

Heat shrink tubing is manufactured through a multi-step process, Material Selection, Extrusion, Cross-linking, Expansion, Cutting, and Packaging.
